Privacy Policy

Last Updated: December 5, 2025

Hemline ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how your personal information is collected, used, and disclosed by Hemline.

1. Information We Collect

1.1. Location Data

We collect your precise location data (latitude and longitude) to provide you with accurate local weather forecasts. This data is fetched only when you use the app or when a background refresh is triggered. We do not store your historical location data on our servers; it is processed locally on your device and sent to our weather data provider to retrieve forecast information.

1.2. User Preferences

We store your personal preferences locally on your device to customize your experience. This includes:

This information is stored securely on your device and is not transmitted to our servers or any third party, except as part of the prompt sent to our AI service provider (OpenAI) to generate personalized advice.

1.3. Usage Data

We may collect anonymous, aggregate usage data to help us improve the app's performance and user experience.

1.4. Payment Information

Our app offers In-App Purchases (subscriptions). All financial transactions are processed directly by Apple through the App Store. We do not collect, store, or have access to your credit card information or billing details.

2. How We Use Your Information

3. Third-Party Services

3.1. OpenAI

We use OpenAI's API to generate the "savage" and witty advice text. When you request advice, we send a text prompt containing your current weather conditions and your style preferences (e.g., "Wavy hair, hot weather") to OpenAI. We do not send your precise location coordinates or any personally identifiable information (PII) to OpenAI.

OpenAI Privacy Policy

3.2. Weather Data Provider

We use a third-party weather service to fetch forecast data based on your coordinates.
